Okay I picked some brains at ATI and this was the response I got over the
codec deal. Whether it will help you figure out whats wrong or not I dont
know but seems I was right that in general ATI drivers dont just replace
other codecs. Isnt much info but hopefully it can help you
----Reply I recieved----
....the WDMs and possibly MMC are the only likely sources of additional
codecs that I am aware of at the moment. And lets not forget the DVD decoder
download.
Of course if the problems are related to WMV files perhaps the Media Encoder
pre-requisite for MMC is involved. (Yes, I realize the problem is with movie
maker, but it is difficult to know all interdependancies is this day and
age.)
However, it is likley that something was removed prior to the driver install
and not replaced. Thus leading to a problem. Particularly if someone had
used MMC and subsequently used the ATI Software uninstall.
